In our school we have a small gymnastics hall and a large gymnastics hall. We have the large gymnastics hall on Thursdays and the small one on Mondays.
I choose to write about the large one, because I train ultimate frisbee there.
In the gymnastics hall we have four dressing room. In the dressing room we have some showers and a toilet. If you want to you can put a wall in the middle of the hall.
